That's a quite a big jump. 1.10.1 is from July 16, 2018!

I'm not positive, because your method of getting the folder list is a
little... unique, and completion was also changed slightly between 1.10.1
and now.
However, it looks like the IMAP server is not handling the LIST-EXTENDED
extension properly (rfc5258), i.e. the "RETURN (CHILDREN)" suffix on the
above LIST command. This was added in Mutt 1.12.
If you compiled 2.2.16 yourself, would you mind adding this hack patch
to disable the extension for you and see if that fixes things:
